Procurement Notes
Verify the specific voltage rating requirement against the 760VAC specification before procurement. Confirm that the M6 threaded post termination matches the existing panel or busbar design. Ensure the 25A continuous current rating aligns with the load profile. Check for any regional distribution restrictions as availability may vary by location.
Selection Notes
Select this model when high-voltage three-phase filtering is required. The two-stage design offers superior attenuation compared to single-stage units. Consider the physical dimensions and mounting requirements for the M6 terminal interface. Evaluate the leakage current characteristics to ensure compliance with safety standards for the intended installation environment.
